In the spring of Ningbao's thirteenth year, the city of Yangzhou lost the sea of flowers but gained a girl on the first floor of the Hong Pavilion who was a thousand times prettier than the sea of flowers. But the girls in the Hong Pavilion only knew that their beauty was not as good as that of the boy who kept the fire in the woodshed - Xiao Man. In the world of martial arts, he was the number one merchant in Yangzhou City; in the temple, he was the seventeenth prince who assisted the emperor in government affairs. Two people who have nothing in common met, got to know each other, and fell in love due to the pull of fate. However, the real reason why Xiaoman concealed his identity and the intervention of Ming Nie'an, who has a deep affection for Xiaoman, also made the future of the two full of uncertainties.
